21) (5 points) The surface tension of ethanol (CHCH2OH) is 0.022 J/ m2 and the surface tension of hexane (CH3CH2CH2CH2CH2CH3) is 0.0179 J/m2. Define surface tension and explain why the values for the listed molecules are different.

Sulfur exhibits two solid phases, rhombic and monoclinic. Use the accompanying phase diagram for sulfur given below to answer the questions that follow. (A).    How many triple points are in the phase diagram?  (B).   What phases are in equilibrium at the topmost triple point?   (C).   How many phase transitions are there when rhombic sulfur at 1 atm and 80°C is heated to 500°C at constant pressure?

Please answer the following question about a lab experiment about synthesizing aspirin. The procedure for this experiment is included in the photos. If after reheating the aspirin/ethanol/water mixture, the crystals do not appear upon cooling, why would boiling off some solvent make the crystals appear?

The vapor pressure of pure H20 depends on what?

The approximate molar mass of a volatile liquid can be determined by:1. Heating a sample of the liquid in a flask with a tiny hole at the top, which converts the liquid into gas that may escape through the hole2. Removing the flask from heat at the instant when the last bit of liquid becomes gas, at which time the flask will be filled with only gaseous sample at ambient pressure3. Sealing the flask and permitting the gaseous sample to condense to liquid, and then weighing the flask to determine the sample’s mass as shown.
